Specification of Letters Patent. Patented 113 24 1914 application filed December 11, 1911. a Serial No. 665,021.

To all whom it mag concern Be it known that I, LEWIS C. BAYLES, a citizen of the United States,'and-resident.of Eastoinin the county of Northampton and State of Pennsylvania, have invented a new and useful Improvement in Fluid-Pressure- Operated Hand-Tools,-of which the following is a specification.

The object of my invention is to provide a fluid pressure operated hand tool, such, for instance, as a riveting or chipping ham 'mer in which the cylinder and its handle are bolted together thereby doing away with the screwed and clamped construction usually employed -and obviating entirely all danger of slipping between the handle and cylinder.

A further object is to provide a tool of the above character which will present a very neat and attractive appearance, the bolts being arranged in alinement with the handle grip and housed within the handle and cylinder.

A still further object is to provide certain improvements in the construction, form and arrangement of the several parts whereby the fastenlng bolts are locked against unintentional displacement between the cylinder andhandle, the bolts being so secured that they cannot be inserted or removed without the'removal of the cylinder from the handle.

A practical embodiment of my invention is represented in the accompanying draw ings, in which+ I Figure 1 represents in side elevation a portion of a fluid pressure operated hand tool embodying my invention, Fig. 2 is a view of the same partly in longitudinal vertical central section and partly in side elevation, Fig. 3 is'a section taken in the plane of the line AA of Fig. 2, and Fig. 4 is a section taken in the plane of the line B B of Fig. 2.

The handle of the tool is denoted by land the cylinder by 2. The inner end 3 of the cylinder is inserted into the central b0re'4 in the face of the handle and the cylinder is provided with an external flange 5 opposite the face of the handle. The bolts for looking the handle and cylinder together are arranged lengthwise of the tool and in alinement with the handle.v

The handle is provided with oppositely arranged lateral recesses 6 in the walls of the bore 1 for housing theheads 7 of the locking bolts. The handle is further provided with oppositely arran ed longitudinal recesses 8 in the walls of t e bore 41 leadmg from the lateral recesses 6 to the'face of the handle for housing the inner portions of the shanks 9 of the locking bolts. Thev flange 5 of the cylinder is provided with oppositely arranged longitudinal holes 10 through which the shanks 9 of the bolts extend. Nuts 11 have a screw threaded engagementwith the ends of the shanks 9 of the bolts beyond the flanges 5 for reinovably securing the cylinder to 'the handle. Lock washers 12 may beinterposed between the nuts 11 and the flange '5 for preventing the unintentional unscrewing of the-nuts. To more compactly house the parts, the nuts 11 and lock washers 12 may project into recesses 13 in the outer walls of the cylinder 2.

In assembling the parts, the bolts must first be inserted into their lateral and longitudinal recesses in the handle by way of the bore 1 before the inner end of'the cylinder 2 is inserted into the bore. end of the cylinder ;is inserted into the bore to bring its flange against-the;face of the handle, the screw threaded ends of the When the inner shanks of the bolts will be inserted through the holes 10 in the flange, the inner end of the cylinder servin to hold the bolts in their recesses in the andle against unintentional displacement.

It will be seen that the tool constructed as hereinabove set forth may have'its banrigidly securing them together, said bolts having their heads housed within the handle. 2. A hand tool ggiitho character-described comprising a cylinder, its handle and bolts for securing them together, said handle having a central bore and lateral recesses in the Walls of the bore for housing the heads of the bolts.

3. A hand tool of the character described 5 comprising a cylinder, its handle and bolts for securing them together, said handle having a central bore and lateral recesses and longitudinal recesses in the walls of the bore for housing the heads and shanks of the (0 bolts.

4:. A hand tool of the character described comprising a cylinder, its handle and bolts for securing them together, said handle having a central bore and lateral recesses in the Walls of the bore for housing the heads of 15 the bolts, and said cylinder having a flange through which the shanks of the bolts extend and nuts engaging the shanks beyond said flange.

In testimony, that I claim the foregoing 20 as my invention I have signed my name in presence of two witnesses, this seventh day of December 1911.

LEWIS C. BA'YLES.
